Modification of network structure induced by glass former composition and its correlation to the conductivity in lithium borophosphate glass for solid state electrolyte

Composition and structure dependence of the properties of lithium borophosphate glasses showing boron anomaly

“…Lithium borophosphate glasses were first studied by Magistris et al [13], who demonstrated that substitution of B 2 O 3 for P 2 [14][15][16]. Cho et al showed that the addition of P 2 O 5 to lithium borate glasses decreases the room temperature conductivity with a maximum value of 1.6 Â 10 À7 S cm À1 [15].…”

Structure and properties of high Li2O-containing aluminophosphate glasses

“…In particular, phosphate and borophosphate systems were studied by previous authors as candidates for solid electrolytes in lithium-ion secondary batteries. 4,5 Nowadays, glasses and glass-ceramics of the system Li 2 S-P 2 S 5 -P 2 O 5 have shown the highest conductivities, which are in the order of 10 −3 to 10 −5 S cm −1 at room temperature, and best performances as electrolytes in all-solid-state devices. 6,7 The generally poor chemical durability of phosphate glasses has limited their practical application in real systems.…”

New Developments in Solid Electrolytes for Thin-Film Lithium Batteries

“…Solid electrolytes are a key material of all-solid-state energy storage devices and have been extensively studied in the fields of materials science (Scholz and Meyer, 1994), polymer science (Croce et al, 2001;Fauteux et al, 1995;Song et al, 1999), and electrochemistry (Scholz and Meyer, 1994). Much research has been devoted to the preparation of solid electrolytes made of various materials including ceramics (Abe et al, 2005;Jak et al, 1999a;Jak et al, 1999b), glasses (Iriyama et al, 2005;Lee et al, 2002;Lee et al, 2007;Takada et al, 1995) and glass ceramics (Hayashi et al, 2010;Minami et al, 2011;Ohtomo et al, 2005).…”
